RE: Pattern of Violations, Coal Basin Mines (C-81-017)
A review of enforcement actions during 1989 at the Coal Basin Mines, operated
by Mid-Continent Resources, Inc. , indicates that a Pattern of Violations may
exist. Five Violations and one Cessation Order have been issued between
February and November of 1989. The CO and three NOV's are through
administrative review and are final , while two additional NOV's are recent and
have just begun the assessment process.
NOV C-89-003 was issued on February 22, 1989 for failure to maintain
facilities to treat water discharges from an underground mine and related
performance standards. The pond series 016, which treats water pumped from
the underground workings, froze due to extreme cold, resulting in
short-circuiting of the ponds. Values of Total Suspended Solids of
6800 mg/l (1/26/89), 5400 mg/1 (2/2/89) , and 3100 mg/1 (2/23) were obtained,
compared to the NPDES permit limits of 35 mg/1 monthly average and 70 mg/l
maximum. The NOV was terminated on May 4 following installation of temporary
sediment control , weekly monitoring of effluent from 016, and Division
approval of a Technical Revision for enhanced sediment control . A Civil
Penalty of $850.00 resulted from an assessment conference.
NOV's C-89-013 and C-89-017 resulted from an inspection on May 24, 25,
and 26, 1989. C-89-013 was for a violation of permit approval . A small-area
exemption had been granted for an area under the raw coal conveyor belt, on
the condition that no coal spillage take place. Coal spillage had occurred,
however, and abatement consisted of cleaning of the spilled coal and
installation of an approved sediment control system for the area. The
violation was terminated on July 19, and an assessment conference led to a
civil penalty of $1050.00.
C-89-017 was written on the same date as C-89-013, for Failure to construct
appropriate sediment control measures to prevent additional contributions of
sediment to streamflow, and Failure to pass surface drainage from the
disturbed area through a sediment pond or treatment facility. A
newly-constructed topsoil stockpile had no sediment control installed.
The violation was terminated on July 6, 1989, following installation of
approved sediment control measures. An assessment conference resulted in a
penalty of $300.00.
